Pros: First off, I really liked the design and was worried about the air flow.. but it surprised me the way the air flows through this. I have a corsair 120mm high performance fan in the front with another 120mm corsair quiet edition red led... keeps the case nice and cool.
I installed a h80i GT onto the cpu with duel fans on the radiator which keeps my 8350 nice and cool overclocked. I have it at 4.6 and under load for a hour and half of playing games didn't even break over 50c.. Ok so the case was fun to build with and looks really cool. Good mid size case better of the ones I've worked with. So GOOD AIR FLOW , Nice HDD Trays , Plenty room in back with zip tie mounts to hide wires. Cable management is very good with this one friends.

Cons: There only a few cons, for one the back plate for pci slots once you break them off I couldn't get it to stay back so be sure thats where you want to put things like your card though I did like the latch on the back. Be careful with a big psu and atx motherboard because I ended up with literally no clearance between them. There just enough space there for them not to touch. This case sponsored to me from the company...but I would have bought for the price and what I got in it , it keeps up with my main rig with less space.

Other Thoughts: IN WIN is a great company the people are respectful and that goes along way in my book. They answer questions and have really nice cases. This mid size case was perfect for the space I had and will keep my kids happy because now they have there own little beast of a machine thanks

Hello Tyler,

Thank you for leaving feedback on our 503 chassis. We are happy to read that you really enjoyed building out of the 503 and it exceeded expectations. As for the few suggestions you had, we'd be more than happy to forward them to our R&D department for future product consideration. Thank you for choosing In Win.

Pros: Looks great, works especially well with any red/black build. Very well priced, originally I was going to spend $350 on a new PC case but when I saw this for only $55 I couldn't resist. The case seems to make my build quieter than it was before too.

Cons: Not a lot of fan mounts, decreased airflow, front of the case has 2 fan mounts but only 1/3 of one can receive air flow. No rubber feet but that's a matter of a $4 purchase at the arts and crafts store and some glue.

Other Thoughts: Would highly recommend to anyone on any sort of budget build, if you want a good looking case for under $100 this is the case. Would not recommend for anything with a custom loop or anyone with a cooling that requires 2 or more adjacent fan mounts (only 120mm radiators will work in this build).
